To provide comfort in your home, one of the solutions is to equip a water floor heating, so it is important to decide in advance which pipes choose for a water-heated floor.
Also, a water-heated floor does not require large operating costs.
Therefore, more and more often water heated floors began to be used, besides, they became an independent source of heat in houses.
The durability and quality of a water floor system is directly dependent on materials and installation.
To make the choice of pipes for the thermal water floor correct, we have written this article and will analyze the selection features further.
And the installation of water heating pipes is best left to specialists. And so on, consider what pipes should be for a warm water floor.
Positive qualities in aquatic Heated floors are more than enough.
Water heated floors have the following positive qualities :
Heating with a water-heated floor is easier to organize in a private house, but in a multi-storey building such heating is very difficult.
In the latter case, you will need to reconstruct an existing system or install your own electric boiler, this is necessary so as not to disrupt the heating of the entire building and not take heat from your neighbors.
The durability and reliability of a water-heated floor depends heavily on pipes that will remain intact under the screed layer for many years.
The following requirements are imposed on pipes :
Be sure to choose pipes only for a water heated floor and companies that give a guarantee of fifty years or more;
For water floor heating systems use :
According to the norms, cast-iron pipes cannot be used for a warm water floor.
Reinforced-plastic pipes are very popular. They are considered durable and also have good performance.
Pipes made of metal-plastic have a multilayer structure. The layer on the inside is polyethylene, crosslinked by extrusion, which is responsible for the characteristics of the pipes.
Then comes a layer of aluminum, it is glued to the polyethylene with glue.
To prevent oxygen from penetrating inside the pipe and to contain linear contractions and expansions, aluminum foil is inserted into the pipe.
The foil layer should be 0.2-0.25 mm, it depends on the diameter.
Due to the fact that the foil is welded in a joint or overlap, a layer is released that has airtightness.
There is another layer of glue on top of the foil, which connects it to the protective layer of polyethylene, which is located outside.
This structure of metal-plastic pipes has a lot of advantages :
Among the minuses is that they cannot be twisted and bent with respect to the axis, which must be remembered.
It is very important to take into account the property of the aluminum layer; it is damaged by repeated bending.
Cross-linked polyethylene pipes are a competitor to metal-plastic pipes.
The main quality of the product is the quality of the seam, which is judged by the density of the stitching. The optimal value is 60-85%.
Processing is done in different ways :
These pipes are marked as PE-Xa;
There are the following pipe markings :
Negative qualities :
Copper, in terms of performance, is an ideal material for equipping underfloor heating.
Positive qualities :
Copper pipes also have some disadvantages :
These stainless pipes are used less often than copper ones, despite on a number of advantages.
These products have a long service life, as well as good thermal conductivity, excellent bend , durable, do not corrode. But these pipes are not very cheap.
The disadvantage of such pipes is the limited service life of rubber bands for sealing.
Polypropylene pipes are an order of magnitude cheaper than copper pipes, steel pipes and metal-plastic pipes, but for some reason they are not widely used.
Pipes marked PN25 are used for underfloor heating, they are reinforced with perforated aluminum foil.
The outer diameter of the pipe is from 21 to 78mm, and the wall thickness should be from 4 to 13mm.
Positive qualities :
Negative qualities :
Installation of polypropylene pipes is done at temperatures above + 10- +15 degrees, but this does not always work.
Well, we told you about the pipes of the warm water floor and we hope that the information will be necessary for you. We wish you good luck and patience!
